A Universal Reference Sample Derived From Clone Vector For Improved Detection Of Differential Gene Expression, Rishi L. Khan, Gregory E. Gonye, Guang Gao, James S. Schwaber

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Background

Using microarrays by co-hybridizing two samples labeled with different dyes enables differential gene expression measurements and comparisons across slides while controlling for within-slide variability. Typically one dye produces weaker signal intensities than the other often causing signals to be undetectable. In addition, undetectable spots represent a large problem for two-color microarray designs and most arrays contain at least 40% undetectable spots even when labeled with reference samples such as Stratagene's Universal Reference RNAs^TM.

Results

We introduce a novel universal reference sample that produces strong signal for all spots on the array, increasing the average fraction of detectable …

Level I Fieldwork Today: A Study Of Contexts And Perceptions., Caryn Johnson, Kristie P. Koenig, Catherine Verrier Piersol, Susan E. Santalucia, Wendy Wachter-Schutz

Department of Occupational Therapy Faculty Papers

The last comprehensive examination of the Level I fieldwork experience was performed 15 years ago (Shalik, 1990) and addressed the different types of settings in which fieldwork occurred; amounts and types of supervision; structure and scheduling of the Level I experiences; and the effects of supervising Level I students on productivity. Although every occupational therapy and occupational therapy assistant student encounters a number of Level I fieldwork opportunities, little is available describing the process and contexts of the Level I fieldwork experience today. This study, which examines 1,002 student reports on Level I fieldwork experiences, finds that Level I fieldwork …

Role Of Caveolin-1 In The Regulation Of The Vascular Shear Stress Response, Philippe G. Frank, Michael P. Lisanti

Department of Cancer Biology Faculty Papers

In blood vessels, endothelia are submitted to constant shear effects and are, under normal conditions, capable of responding to any variation in hemodynamic forces. Caveolae — 50- to 100-nm plasma membrane invaginations present at the surface of terminally differentiated cells and particularly enriched in ECs — are composed of a high sphingolipid and cholesterol content and the protein caveolin-1 (Cav-1). Previous studies have suggested that caveolae and endothelial Cav-1 may regulate the vascular response to altered shear stress. In this issue of the JCI, Yu et al. have examined the role of Cav-1/caveolae in the regulation of flow-induced alterations (i.e., …

Light During Darkness And Cancer: Relationships In Circadian Photoreception And Tumor Biology, Samar A. Jasser, David E. Blask, George C. Brainard

Department of Neurology Faculty Papers

The relationship between circadian phototransduction and circadian-regulated processes is poorly understood. Melatonin, commonly a circadian phase marker, may play a direct role in a myriad of physiologic processes. The circadian rhythm for pineal melatonin secretion is regulated by the hypothalamic suprachiasmatic nucleus (SCN). Its neural source of light input is a unique subset of intrinsically photosensitive retinal ganglion cells expressing melanopsin, the primary circadian photopigment in rodents and primates. Action spectra of melatonin suppression by light have shown that light in the 446–477 nm range, distinct from the visual system’s peak sensitivity, is optimal for stimulating the human circadian system. …

Mixed Germ Cell Sex Cord-Stromal Tumors Of The Testis And Ovary. Morphological, Immunohistochemical, And Molecular Genetic Study Of Seven Cases, Michal Michal, Tomas Vanacek, Radek Sima, Petr Mukensnabl, Ondrej Hes, Dmitry V. Kazakov, Jozef Matoska, Anna Zuntova, Vladimir Dvorak, Alexander Talerman

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

We present the morphological, immunohistochemical, and molecular genetic features of three cases of testicular and four cases of ovarian mixed germ cell sex cord-stromal tumors (MGSCT). The germ cells in the testicular MGSCTs morphologically differed from those in classical seminomas by lacking the typical "square off" quality of the nuclei. In contrast to the nuclei in classical seminomas, their size in testicular MGSCTs was smaller and nucleoli were inconspicuous and the cytoplasm was Periodic Acid-Schiff(PAS) negative. Quite on the contrary, the variability in the size of the nuclei of the germ cells in the testicular MGSCTs was more similar to …

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Background

Validation of a novel gene expression signature in independent data sets is a critical step in the development of a clinically useful test for cancer patient risk-stratification. However, validation is often unconvincing because the size of the test set is typically small. To overcome this problem we used publicly available breast cancer gene expression data sets and a novel approach to data fusion, in order to validate a new breast tumor intrinsic list.

Results

A 105-tumor training set containing 26 sample pairs was used to derive a new breast tumor intrinsic gene list. This intrinsic list contained 1300 genes …

Scientific Issues Related To The Cytology Proficiency Testing Regulations, George Birdsong, Lydia Howell, Karen Atkinson, R. Marshall Austin, Marluce Bibbo, Thomas A. Bonfiglio, Diane D. Davey, Catherine Keebler, Dina Mody, Lynnette Savaloja, Jacalyn Papillo, Marianne Prey, Stephen Raab, Brenda L. Schultz, Diane Solomon

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

The member organizations of the Cytology Education and Technology Consortium believe there are significant flaws in current cytology proficiency testing regulations. The most immediate needed modifications include lengthening the required testing interval, utilizing stringently validated and continuously monitored slides, changing the grading scheme, and changing the focus of the test from the individual to laboratory level testing. Integration of new computer-assisted and located-guided screening technologies into the testing protocols is necessary for the testing protocol to be compliant with the law.

Data And Safety Monitoring In Social Behavioral Intervention Trials: The Reach Ii Experience, Sara J. Czaja, Richard Schulz, Steven H. Belle, Louis D. Burgio, Nell Armstrong, Laura N. Gitlin, David W. Coon, Jennifer Martindale-Adams, Julie Klinger, Sidney M. Stahl

Center for Applied Research on Aging and Health Research Papers

Background Psychosocial and behavioral interventions trials targeting a broad range of complex social and behavioral problems such as smoking, obesity and family caregiving have proliferated in the past 30 years. At the same time the use of Data and Safety Monitoring Boards (DSMBs) to monitor the progress and quality of intervention trials and the safety of study participants has increased substantially. Most of the existing literature and guidelines for safety monitoring and reporting of adverse events focuses on medical interventions. Consequently, there is little guidance for investigators conducting social and behavior trials.

Purpose This paper summarizes how issues associated with …

Voltage-Dependent Gating Rearrangements In The Intracellular T1-T1 Interface Of A K+ Channel., Guangyu Wang, Manuel Covarrubias

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

The intracellular tetramerization domain (T1) of most eukaryotic voltage-gated potassium channels (Kv channels) exists as a "hanging gondola" below the transmembrane regions that directly control activation gating via the electromechanical coupling between the S4 voltage sensor and the main S6 gate. However, much less is known about the putative contribution of the T1 domain to Kv channel gating. This possibility is mechanistically intriguing because the T1-S1 linker connects the T1 domain to the voltage-sensing domain. Previously, we demonstrated that thiol-specific reagents inhibit Kv4.1 channels by reacting in a state-dependent manner with native Zn(2+) site thiolate groups in the T1-T1 interface; …

Pro-Opiomelanocortin Co-Localizes With Corticotropin-Releasing Factor In Axon Terminals Of The Noradrenergic Nucleus Locus Coeruleus, Beverly A.S. Reyes, Julia D. Glaser, Ronaldo Magtoto, Elisabeth K. Van Bockstaele

Department of Neurosurgery Faculty Papers

We previously demonstrated that the opioid peptide, enkephalin, and corticotropin-releasing factor (CRF) are occasionally co-localized in individual axon terminals but more frequently converge on common dendrites in the locus coeruleus (LC). To further examine potential opioid co-transmitters in CRF afferents, we investigated the distribution of proopiomelanocortin (POMC), the precursor that yields the potent bioactive peptide, ß-endorphin, with respect to CRF immunoreactivity using immunofluorescence and immunoelectron microscopic analyses of the LC. Coronal sections were collected through the dorsal pontine tegmentum of rat brain and processed for immunocytochemical detection of POMC and CRF or tyrosine hydroxylase (TH). POMC-immunoreactive processes exhibited a distinct …

Light Therapy For Seasonal Affective Disorder With Blue Narrow-Band Light-Emitting Diodes (Leds), Gena Glickman, Brenda Byrne, Carissa Pineda, Walter W. Hauck, George C. Brainard

Marcus Institute of Integrative Health Faculty Papers

Background: While light has proven an effective treatment for Seasonal Affective Disorder (SAD), an optimal wavelength combination has not been determined. Short wavelength light (blue) has demonstrated potency as a stimulus for acute melatonin suppression and circadian phase shifting.

Methods: This study tested the efficacy of short wavelength light therapy for SAD. Blue light emitting diode (LED) units produced 468 nm light at 607 µW/cm2 (27 nm half-peak bandwidth); dim red LED units provided 654 nm at 34 µW/cm2 (21 nm half-peak bandwidth). Patients with major depression with a seasonal pattern, a score of ≥20 on the Structured …
